Description of the machine
Operating mode
When the compressor is activated, the drier also starts
after a pre-set delay. Alarms are inserted with delay to
allow the drier to reach its operating mode. Once this
delay has elapsed, the alarms start and begin monitoring
the system. Once started, the dryer compressor group
stays on until the following conditions occur:
– The compressor is stopped with the “STOP” push-
button;
– He dryer operating limit conditions are exceeded.
The controller manages the dryer operation by
monitoring the dew point temperature that allows the
system to run correctly. The operating limits for such a
parameter are as follows:
– The dew point temperature > T. Stop;
– The dew point temperature < 6°C with Ambient
Temperature ≤ 25°C;
– The dew point temperature < T.amb. – Δ ambient
with Ambient Temperature > 25°C.
MATTEI sets the Δ ambient value.
If the dew point drops below T. Stop, the controller
will indicate the faulty condition [Ice Alarm] while the
dryer compressor is kept active throughout the time
corresponding to the parameter [Low Temperature
Delay Time]. Once this time has elapsed, the dryer
compressor is stopped so to prevent any ice from forming.
As soon as the temperature rises again above T. Start,
the dryer compressor is re-started and the fault warning
is automatically turned off.
Should the dew point temperature rise above the upper
limit, the controller will indicate the fault condition
[
ALARM
High Dew Point] for the time that corresponds
to the parameter [
High Temperature Delay Time
]. When
the set time has elapsed, the alarm warning will stay on.
As soon as the temperature falls again within the above-
mentioned operating interval, the fault warning will be
automatically turned off

NOTE: The user can request Ing. ENEA MATTEI
that the fault in the dryer corresponds to a
machine bLOCK.
F
NOTE: The design of the dryer prevents
condensate from accumulating and ice from
forming inside it. In case of any failure in the
dryer, by-passing the device is possible by
disconnecting the hose linking it to the air
radiator and connecting it directly to the
delivery side. All joints installed are
equivalent.
